Good afternoon, colleagues!
I have a problem with association of a stack cisco WS-C2960RX-48FPS-L . 6 switches integrated, 2 more did not integrate.
I changed stack module, cable stack, priority, provision, renumber, fully cleared all configs to make switches as from factory, changed firmware. However the problem did not disappear.
Tried on ios 15.2.4.e3, 15.2.4.e7, 15.2.6.e2.
If it's necessary I will send a config. Help me!!! Thank you!

Hi,
It seems there are two different stacks are operating and Stack ports are showing down. Have you verified all stack cables? Are connected in the correct order? Have you verified Switch number configuration?
Share the configuration and some logs as @paul driver requested.

Hello
Make sure all switch support the same software/feature set
Are you using the correct cabling?
Are the cabled in the correct way?
sh switch detail
sh switch stak-ports

quick look - I may be wrong, your output some switches uptime different time, some are less uptime.
have you rebooted complete stack ?

Hi, Yes, I rebooted the full stack at the same time.

Other suggestion was mentioned by @paul driver , you can try that option.
Connect the console cable to master switch (keep logg all the logging of the console so we can see what is wrong)
1. Turn on the Master switch1 ....after minute Turn on swtch 2 ---so on once all booted.
2. show switch
3. post the logs to forums to have a look.

I did as you advised, disconnected the stack modules, wires, after connecting the first stack, I waited 40 sec and started connecting the stack wires and the follower switch. I attach the config all left without changes =(
